Crystals Procurement Notes

Verify the specific ordering suffix against official CTS documentation to ensure the correct frequency tolerance and packaging configuration. Confirm that the required ESR and load capacitance values align with the target circuit design before finalizing procurement orders. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required with a 20 pF load capacitance. Ensure the application environment remains within the specified -20°C to +70°C operational range. Verify that the 60 Ohm ESR is compatible with the driving circuit's oscillation requirements and that the 4-SMD footprint matches the PCB layout constraints.

Crystals Part Context

This part belongs to the CTS 405 series of surface-mount crystals, designed for general-purpose timing applications. The series provides various frequency options in standardized packages to facilitate design reuse across different product lines.
